Two gestational sacs and one empty sac are considered to be carrying twins, but one of the embryos has stopped developing. If two gestational sacs are found after pregnancy, it means that there are two fertilized eggs, i.e. twins, but if one of the sacs is found to be empty, it means that the embryo has ceased to develop and self-elimination has occurred. If one of the two gestational sacs is empty, but the other gestational sac is developing normally, and the pregnant woman is not experiencing any discomfort, the pregnancy can continue. If the pregnant woman has abdominal pain or bleeding and other abnormalities, she should go to the hospital in time. It is recommended to keep a relaxed mood and go to the hospital for regular checkups to keep an eye on the baby’s development.
